Segmentation of the same object in different view

In this paper, we propose an object segmentation method to extract the same object from images that are captured from different views. Using matting method, the target object can be easily segmented with simple strokes given by a user to the desired object and background in the reference image. Then, homography is estimated after keypoint matching between the segmented object image and the target image, which is acquired from a different viewpoint, containing the same object. Using homography, the strokes are transformed to fit to a target image. Finally, the identical object is segmented from the target image using matting method with transformed strokes. The proposed method can be used to increase the accuracy of segmentation for extracting the same desired object from a target image.
